Description
Technical field
The present invention relates to a kind of novel polyvinyl-chloride use processing aid and preparation method thereof.
Background technology
Polyvinyl chloride (PVC) is a kind of important commodity polymer material, and since the thirties in 20th century, its field such as plastic window frame in film, sheet material, tubing and exploitation in recent years is widely used.Owing to having defective in the PVC molecular structure, its flow temperature and decomposition temperature approach, and contain two keys, branch point and initiator residue etc. in its molecular structure, add man-hour under high temperature and shear conditions, easily slough the HCl on molecule and cause polymer degradation, color burn, mechanical property reduces, until lose use value.The method that overcomes these defectives has two kinds, and the one, add thermo-stabilizer, improve the thermal stability of PVC; The 2nd, add processing aid, reduce its plasticization temperature.
The processing aid of low molecular mass and the consistency of PVC are poor, auxiliary agent can move, and causes product properties, permanent stability and dimensional stability to reduce, the lost of life, this will inevitably affect the steady progression of PVC material, and environment and recovery are brought heavy pressure.Generally acknowledge that at present best processing aid is mainly ACR, its good processability, weather resistance is excellent, and shock strength is high.But its complex manufacturing, cost is high, and the ACR performance that different copolymerization compositions can cause obtaining differs greatly, and also therefore can cause the control disadvantageous effect quality of item to its consumption and processing temperature.
Summary of the invention
The object of the invention is to prepare a kind of low cost, stable performance, can improve polyvinyl chloride processing aid of goods processing characteristics and preparation method thereof.
The technical solution adopted in the present invention is: a kind of polyvinyl-chloride use processing aid, contain polyacrylic ester (ACR), terephthaldehyde's acid metal salt, clorafin, polyvinyl chloride.
As preferably, described terephthaldehyde's acid metal salt is selected from one or more in terephthalic acid calcium, terephthalic acid magnesium, terephthalic acid zinc, potassium terephthalate, para-phthalic sodium, terephthalic acid barium, terephthaldehyde's lead plumbate, terephthalic acid aluminium, terephthalic acid iron.
As preferably, the mass ratio of polyacrylic ester (ACR), terephthaldehyde's acid metal salt, clorafin, polyvinyl chloride is 25-50: 30-55: 5-10: 5-10.
As preferably, vector resin, terephthaldehyde's acid metal salt, silane coupling agent and and the mass ratio of lubricant be 25-40: 50-70: 7-8: 7-8
The prilling process of aforementioned processing aid, its processing step is: by proportioning terephthaldehyde's acid metal salt and polyacrylic ester are turned at 500-1000 in stirring tank/stir 4min under min, jump to again at 4000-5000 turn/min under high-speed stirring 5min, change 1500-2000 to turn/min under middling speed slowly add clorafin, stir 5min, add again vector resin, stir hot melt mix and blend 10min under 150 ℃, the material that to process at last extrudes under 90-100 ℃, fervent, air-cooled, namely get gained processing aid product of the present invention.
Processing aid provided by the invention can promote the plasticizing of polyvinyl chloride (PVC), reduces its melt viscosity, reduces energy consumption and production costs; When improving the PVC processing characteristics, can improve the flame retardant properties of PVC goods; Improve surface smoothness and the ageing-resistant performance of goods, guarantee the performance steady in a long-term of goods; Price has reduced the material cost of source mill lower than ACR.
